'Big Bang Theory' Taps 'Roseanne' Alum as Bernadette's Mother

Meagen Fay will play Mrs. Rostenkowsi and guest star alongside Casey Sander in a December episode of the CBS comedy.

Howard Wolowitz (Simon Helberg), prepare for more awkward family dinners.

The returning payload specialist is poised to make up for lost time and sit down for a Rostenkowski family dinner on CBS' The Big Bang Theory, breaking bread with not only Bernadette's (Melissa Rauch) ex-military father (played by Casey Sander) but also his new bride's mother.

The casting marks the latest Lorre series for Fay, who in addition to playing Roseanne's stuffy neighbor Kathy Bowman, has also guest starred on Lorre's Two and a Half Men. Her credits also include Malcolm in the Middle, The Bernie Mac Show and more recently The Neighbors and Retired at 35.
